LESSON PACKET / SA-EDA-FLOORPLAN-001

Floorplan choices show up as report pressure.
EDA / Layout

EDA learning should not be only a command checklist. This packet keeps utilization, aspect ratio, macro channels, PDN strategy, clock topology, routing congestion, IR-drop, skew, and timing-risk evidence in one bounded browser replay.

EVIDENCE SEQUENCE

What the learner should inspect first.

This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.

01

Start with utilization, aspect ratio, macro strategy, and report stage before reading any single QoR number.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
02

Compare placement overflow, RUDY-style congestion, global-route overflow, PDN obstruction, IR-drop risk, current-density risk, skew, insertion delay, and slack-risk proxies together.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
03

Use the decision gate to choose the next safe report check: floorplan sizing, macro channels, PDN/IR, CTS, global route, or owned-report review.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

METHODS

Precomputed model contract.

The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.

method

Original synthetic floorplan report-literacy table based on official public OpenROAD/OpenLane vocabulary.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

No DEF, GDS, SPEF, SDC, Liberty, PDK, report file, or flow script is copied or parsed.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

The browser filters saved CSV rows and exposes the model card with no-live-flow and no-signoff boundaries.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

LIMITS

Useful, but deliberately bounded.

No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.

non-claim

No live OpenROAD, OpenLane, OpenSTA, Magic, Netgen, PEX, SPICE, field solver, uploaded design, PDK redistribution, or signoff service.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

No routing guidance, timing closure, PDN signoff, tapeout readiness, foundry qualification, or product claim.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

Real work needs owned design databases, exact tool versions, legal PDK authority, STA/PDN/routing reports, and design-owner review.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

SOURCE ANCHOR

Link-only public source spine.

SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
